Love Alarm revolves around the story of a disruptive technology that enables users to discover love through an application that notifies whether someone within the vicinity of a 10-meter radius has romantic feelings for them. If someone likes you and they are within 10 meters of you, the alarm for the app rings. The app also shows how many people like you, but the app doesn't reveal specific details on who likes you. Son Hwa Min is a high school student. She is pretty and smart. She seems like cheerful person, but her parents died when she was young. Since the death of her parents, Son Hwa Min has lived with her aunt's family. Living there is not easy for her. She doesn't download the app. Meanwhile, (Muse b guy) is a popular male student at the same high school where she attends. He is the son of a wealthy family, but he is not loved by his parents. His best friend Lee Hye-Young also attends the same high school. (Muse b guy) notices that his best friend Lee Hye-Young is dating Son Hwa Min. ((So basically its about Muse A girl who is a troubled high school student. She works three jobs to pay off her mothers debt that was left to her aunt that she now lives with. Her parents killed themselves when she was little, due to being poor and miserable. They tried to kill Muse A girl with them but they didn't add in enough poison to her food. So she woke up to their dead bodies, smoke filling the room because her father taped up all the windows and set a fire so that they would suffocate and eventually burn. It's a horrible background lmao. But then we have her in high school as I said and the app ends up spreading like wildfire. Its called Love Alarm, its main purpose is to tell its user when someone that likes them is in the 10 meter radius, a small heart popping up on the screen and a ding sounding.
